ぞれ独立して制御するように個別に設けられている。In the conventional plant monitoring and control system described above, in the case of the system configuration shown in Fig. 2, even if there is a request to increase the number of master station TC/TM devices, the communication control device in the central processing unit cannot be used. Due to line capacity limitations, it may be impossible to connect a large number of master station TC/TM devices, and in the case of a system configuration as shown in Figure 3,
It is necessary to switch between the active and standby devices of the duplicated master station TC/TM devices for each master station TC/TM device, which may make the switching method complicated, or the network inside the central processing bag may need to be switched. When a failure occurs in the control device, the failure spreads to the entire network, causing the supervisory control function to go down. [Means for solving the problem] The plant supervisory control system of the present invention has the drawback that TC/TM
The devices are connected to separate main highways for the active system and the backup system, and the network control device is configured to independently control the master station TC/TM devices for the active system and the backup system via the main highway. Separately provided.
このように、親局TC/TM装置を現用系と予備系とし
てまとめて切替えることにより、現用系/予備系の切替
が容易になり、またネットワーク制御装置に障害が発生
しても障害がネットワーク全体に波及することが無くな
る。In this way, by switching the master station TC/TM device as the active system and the backup system at the same time, switching between the active system and the backup system becomes easy, and even if a failure occurs in the network control device, the failure will not affect the entire network. It will no longer spread to

is the master station TC of the system set in the current partition information area 8.
/TM device group 6 devices are used to collect data and output control commands to realize a monitoring control function. In addition, packets are sent and received at fixed intervals for the master station TC/TM device group 7 devices of other systems, and the status of the devices is monitored. Currently, "active system" is set in the current classification information area 8, and the active system master station TC
Assume that data is being collected using six devices in the /TM device group. At this time, when an abnormality occurs in one of the active master station TC/TM devices and the central processing unit 1 detects the abnormality, the central processing unit 1 checks the backup system for the 7 devices of the master station TC/TM device group. do.
